| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot reported that the airplane experienced a total loss of engine power when he applied carburetor heat during a 1-mile final approach to the destination airport. The pilot then performed a forced landing to a field. Although the pilot stated that the engine rpm decreased when he actuated the carburetor heat during the preflight run-up, postaccident examinations revealed no mechanical anomalies with the carburetor or its heat system that would have precluded normal operation. Atmospheric conditions at the time of the accident were conducive to the accumulation of carburetor icing at glide and cruise power. It is likely that the pilot’s delayed use of carburetor heat resulted in a total loss of engine power due to carburetor icing.
Probable Cause: The pilot’s delayed use of carburetor heat while operating the airplane in atmospheric conditions conducive to carburetor icing, which resulted in a total loss of engine power due to carburetor icing during a short final approach.
